Preheat oven to 350°F. Line a baking sheet with parchment paper or greased foil. Set aside for later.
In a medium bowl, whisk together all the dry ingredients: oats, oat flour, cocoa powder, baking powder, baking soda and salt.
In a large bowl, whisk together all the wet ingredients: coconut oil, coconut sugar, maple syrup, flax eggs and vanilla. Whisk until thoroughly combined and resembles caramel.
Add the dry ingredients to the wet ingredients. Whisk until thoroughly combined. Fold in chocolate chips and oats. The dough will be sticky.
Using a 2-tablespoon cookie scoop, scoop balls of cookie dough onto the prepared baking sheet. Using a fork, flatten cookies into a round disc—they will not spread during baking. Optionally, press chocolate chips into the tops of the cookies.
Bake for 8-12 minutes. Mine took 10 minutes. Using a flat, heatproof spatula, carefully lift cookies off the baking sheet and transfer to a cooling rack. If cookies are too soft to lift, allow to set on cookie sheet for 10 minutes, then transfer to a cooling rack. Allow to cool completely. Enjoy! Storing instructions below.
